Fungi present in Antarctic deep-sea sediments assessed using DNA metabarcoding
We assessed fungal diversity in deep-sea sediments obtained from different depths in the Southern Ocean using the internal transcribed spacer 2 (ITS2) region of nuclear ribosomal DNA bymetabarcoding through high-throughput sequencing (HTS). We detected 655,991 DNA reads representing 263 fungal ampli...
